How to calculate reseller profit
Profit is what is left after the sale after all fees and costs.
- Fees = selling price x fee percentage + fixed fee
- Cost = purchase price + shipping + supplies
- Profit = selling price – fees – cost
- Margin = profit / selling price
- Return on cost = profit / cost
- Profit per hour = profit / (minutes / 60)
Worked example
You buy an item for $8.00 and sell it for $35.00. The platform takes 13% plus $0.30, which is $4.85. Shipping is $6.00 and supplies are $0.50, so your costs are $14.50. Profit is 35 – 4.85 – 14.50 = $15.65, a margin of 44.7% and a return of 107.9% on what you spent. If sorting and packing take 15 minutes, the profit is $62.60 per hour of work. At 40 items a month the profit is $626.00. The break-even selling price is $17.01.
Hourly profit is the figure many resellers forget. A $5 profit on an item that takes an hour is a poor use of time, even if the return on cost looks high. Track your time on a few items to get a realistic number, then decide which items are worth sourcing.
